SPECIFICATION forming part of Letters Patent No. 305,378, datedSeptember 16, 1884.

(No modcL) .To @ZZ whom it may concern/.-

Be it known that I, CHARLES E. EATON, of Chelsea, county of Suffolk,State of Massachusetts, have invented an Improvement in Oar-Axles, ofwhich the following description, in connection with the accompanyingdrawings, is a speciiication, like letters on the drawings representinglike parts.

This invention relates to improvements on that class of axles describedin Letters Patent No. 284,194, granted to me on the A4th day ofSeptember, 1883, and has for its object to simplify and perfect theinvention described in said patent.

The nature of my present invention is clearly set forth in the followingdescription, `and is particularly pointed out in the claims.

Figure l is a longitudinal vertical section i of a truss or axlesupportmade in accordance with my invention, it containing a divided axle,whichis shown in full lines,wheels being added to the axle; Fig. 2, across-section on line x, Fig. 1; and Fig. 3, a similar section on line yy of said figure.

v The divided axle A and car-wheels B are of usual construction, exceptthat the inner ends thereof are provided with annular grooves c, toreceive collars g.

The axlesupporting truss is formedin two sections, C 0': each sectionhaving a disk, c, and bearings for the inner and outer portions of thedivided axle,and bars or braces d, preferably formed or cast in onepiece, as shown. One'of the disks is provided at its face, near itsperiphery, with an annular projection, c',

which fits into a corresponding depression in the face of the otherdisk, so that when the sections of the axle-supporting truss areconnected together by means of the bolts e, passing through the disksbelow or within the projection c and secured with nuts c', the saidprojection fits into the depression, to make a more perfect and strongerconnection between said disks, and to prevent any possible vertical playof the parts by reason of wear on the bolts or other contiguous parts.By this construction, also, the* projection and depression are locatedat the portion of the disks that receives the greatest support from thearms or braces d, and the bolts e are passed through bolt-holes in saiddisks, where the latter are of even thickness and strength, whereby thesevere strain towliich such parts are subjected 'is evenly distributedthroughout both disks.

ceive the collar y, L-shaped in cross-section, i

and made up of several parts or sections (see Fig. 2) to form in effectsectional collars with inner iianges,which latter project into theannular grooves a in the divided axle A, to hold the ends of the axleslightly apart, and prevent possible grinding of one on the other whenin use. When the sectional collars are brought together, as shown inFig.1, their combined outer surfaces orperipheries form a smoothcylindrical face to permit a metal ring, g', to be placed between it andthe cut-` away portions of the disks in which said s ectional collarsrest, the cut-away portions being made of sufficient depth to enable theinsertion of said metal ring.

The bearings H, for the inner or adjacent l ends of the divided axleA,Vbesides being cast with the disks c, are braced and connected withthe arms d by means of the braces d.,and

are provided with reservoirs 71, to contain suitwhile saidtruss-sections are likewise prevented from movement on the divided axleaway from the wheels by similar collars, 3, fitting within the outerbearings, 5, in recesses, as shown. The outer bearings, 5, haveoil-reservoirs 4C and .linings of `Babbitt metal, 6, as in the ease ofbearings H, and are further provided with outwardly-projecting rims 7,tting Onto turned portions of the hubs of the wheels B, to strengthenand perfect the relation of parts, and provide against the passage ofdust or sand and the like into the bearings. A packing-annu lus, 8,iitted into an undercut groove, 9, intheI bearings 5, further insuresagainst the entrance of dust, makes a tight joint, and prevents theotherwise abutting surfaces of the hubs and IOO bearings fromend-grinding. Besides serving the primary purpose of preventing end-playof the truss-sections on the divided axle, the collars 7c and 3 lalsoprevent dust from entering the bearings where they are placed.

By the construction of parts described either wheel and its axle-sectionis capable of rotation independently of the other, the parts arestrongly and perfectly connected to obviate end-play, they arestrengthened where strength of parts is most required,the entrance ofdust into the bearings is thoroughly provided against, the lubricationof the parts is provided for in a simple and effectual manner, and sur-1- 5 plus metal is avoided.

I claim- 1. An axle-supporting truss formed in. two sections, havingaxle bearings or supports, and provided with disks c, united together asspecified, said disks having the recesses about the axle-opening,combined with the divided axle having the annular grooves a, and thesectional collars g, resting inthe recesses of the disks and fittinginto the grooves a in thedivided axle,l substantially as specified.

y 2. The combination, with the divided axle and attached wheels, of anaxle-supporting truss formed in two sections, having disks c firmlysecured to each other, as specified, and

.provided with bearings for the divided axle,

which is free to rotate in said truss, and the retaining-collars k and3, secured on each half of the divided axle and engaging eachtrusssection at two points, to prevent end-play of either truss-sectionon the divided axle in either direction, substantially as specified.

3. An axle-supporting truss formed in two sections, having disks cflrmlysecured to each oth er, as specified, and provided with bearingsH, integral with the disks c, for the support of the divided axle, whichis free to rotate in said truss, each of the bearings H having aprojecting rim, 2, combined with the divided' axle A, the wheels B, andthe retaining-collars 7c, secured on the divided axle and havingset-screws 7c and shoulders 7a2, fitting within the rims 2 of thebearings ljl, substantially as described.

4. An axle-supporting truss formed in two sections, having disks c,united together as 5o speciiied,land provided with bearingsrfor thesupport of the divided axle, combined with the divided axle A, theattached wheels B, having hubs with turned portions, as speciied, theprojecting rim 7, formed withl the truss and 5 fitting the turnedportions of the hubs, and the collars 3, tting on the axle and having asetscrew and a shoulder fitting a recess in the outer bearing of thetruss, for the purpose set forth,

5. An axle-supporting truss formed in two sections,united togethersubstantially as specified, and having inner and outer bearings for thesupport of the divided axle, the outer bearing having oil-reservoirswith closed orifices, the projecting rims 7, and packing-annulus, as

speCied, combined with the divided axle A,

having retaining-collars 3, with shoulder itting recesses in the outerbearings, as described, and the wheels B, with hubs having the turnedportions, as and for the purpose set forth. i

6. The combination,with a divided axleand an axle-supporting trusshaving bearings for the support of the axle, of two collars secured toeach part of the divided axle and engaging the truss, to `preventend-play of the divided axle in either direction in said truss,substantially as speciiied.

In testimony whereof Ihave signed my name 8o to this specification inthe presence of two subscribing witnesses.

CHARLES E'. EATON.
